Precision Targeting on the Battlefield Raytheon Rangefinders Ensure Mission Success with Minimal Collateral Damage Raytheon pioneered the development of laser rangefinder technology, starting with the first laser ever built — the flash-lamppumped Ruby laser — in the early 1960s. Since then, Raytheon has remained the dominant supplier/manufacturer of rangefinder lasers for a variety of platforms and missions. These include vehicle and manportable/rifle-mounted implementations. The evolution of rangefinder technology has been driven by two requirements: robust eye safety (to prevent the accidental blinding of friendly troops) and covertness (to remain invisible to the naked eye). These requirements led to the development of a family of Nd:YAG – Raman shifted 1.5micron wavelength rangefinder lasers. These lasers are widely used in today’s Raytheon’s long-standing legacy of delivering battle-hard designators to our troops has been proven once again in Operation Enduring Freedom and Operation Iraqi Freedom. Raytheon has an extensive history in Army designator development and production which includes: • White Knight designator delivered to Army Electronics Command (1969) • AC-130 Gunship Laser Designator/Rangefinder delivered starting in 1970 LTD AN/PAQ-1 • G/VLLD & LTD development for U.S. Army beginning in 1972 • MULE development for USMC beginning in 1976 • Direction Ranging Set Laser MULE AN/PAQ-3 Designator for Navy A6E jet starting in 1976 • 1,500 G/VLLDs, 200 LTDs and 400 MULEs delivered (1980-88) 8 2005 ISSUE 1 • AC-130 LTD/R design upgrade and follow-on production (1989-2002) • AESOP (SOF helicopter) production (1992-96) military platforms: • ELITE Foreign LAVs • BELRF ODS • BELRF IBAS • LRAS3 PM-NV/RSTA • TISS U.S. Navy ELITE Foreign LAVs The successful legacy of delivering battle-worthy rangefinders has ensured the U.S. military superiority on BELRF ODS battlefields all over the world. Following the success with Nd:YAG, Raytheon once again BELRF IBAS proved its leadership in cutting-edge laser technology by developing diode-pumped Er:glass lasers for rangefinders.

The ATFLIR designator is already combat-proven with stellar results in current conflicts. Our diode-pumped composite cavity laser technology is providing the basis for the robust designator design that works in the harshest airborne environments. The ATFLIR laser features a convertible LTD/R AC130 Gunship DRS TRAM A6E bomber AESOP various helicopters pumped Er:glass lasers that use passive saturable absorber Q-switch technology proved a robust solution to a complementary set of rangefinder applications. Among these are the Land Warrior ELRF/DCA and OCSW ATD TA/FCS. Raytheon owns numerous patents related to this technology and is poised to further the proliferation of this technology for future military platforms. • OCSW ATD TA/FCS Lightweight Designator Concept LRAS3 PM-NV/RSTA TISS U.S. Navy Kalin Spariosu kalin_spariosu@raytheon.com cavity for an eye-safe (1,570 nm) pulsed output for rangefinding, in addition to the 1,064 nm special waveform output for the designator task. Following success in the fielding of the battle-proven designator and rangefinder laser systems, Raytheon is now pursuing next-generation lightweight designator development. These next-generation designators will feature ultra compact efficient diode pump technology, novel Q-switch technology, improved conversion efficiency laser diodes, and integrating cavity laser pump geometries/architectures. Raytheon is poised to remain the dominant military laser supplier to our armed forces and to lead technology developments that will enable the next generation of precision guided weapon deployment. • Land Warrior ELRF/DCA Kalin Spariosu kalin_spariosu@raytheon.com
Electro-optical Missile Seekers Sensing, Detecting, Tracking – All In One Small Package Electro-optical (EO) seekers are employed in missiles to provide a means of target sensing, detection and selection and to provide updates of target location for improved pointing for guidance. Fielded systems have, historically, been passive sensors using either atmospheric windows of the medium-wave infrared or long-wave infrared bands for day and night operation of the target’s emissive signature; or semi-active laser (SAL) systems requiring third-party illumination to provide a reflected signal from the target with single or few detector elements. EO missile seekers have now evolved to cost-effective staring arrays with tens of thousands of pixels. The constraints that determine the EO seeker design for a given application are the target characteristics (signature, size, range at acquisition, maneuverability, clutter environment); missile constraints (size, power, maneuverability); and environmental conditions (visibility, accelerations). The variety of EO seeker designs is reflective of the vast differences in requirements ranging from shoulder-launched applications, such as Stinger, and a space intercept application, such as Exo-atmospheric Kill Vehicle (EKV). The earliest EO missile seekers used the signal of a target hot spot, such as jet engine exhaust, combined with a free gyro stabilized gimbal system. Evolution over the decades added reticles for countermeasure rejection, linear arrays for early imaging systems and, starting in the 1980s, a general conversion to focal plane arrays of increasing size, with the anti-armor Javelin and anti-aircraft AIM-9X being examples of early fielded staring systems. Since the mid-1990s, uncooled infrared (IR) systems have been maturing that achieve an even lower cost by leveraging commercial silicon processing for lower sensitivity applications. Seeker control and stabilization approaches have evolved from spinning mass (free gyro) stabilization to a variety of approaches ranging from free gyro stabilized (Rolling Airframe Missile, Stinger, Missile Homing Improvement Program, Brilliant Anti-Tank submunition); instrument stabilized (Javelin, Non Line Of Sight (NLOS)), remotely stabilized (AIM-9X, Joint Standoff Weapon (JSOW)) to fixed-post or body stabilized (EKV, Standard Missile 3). The absolute stability requirements for cooled EO sensors have reduced over time with the short integration times of cooled sensors, resulting in systems that are forgiving to motions in terms of smear. Present-day optical systems use fabrication and design techniques, such as integral mounts, aspheres and diffraction gratings, to achieve system requirements of collection efficiency, bandwidth and performance over temperature ranges within the severe packaging constraints of missile systems. Image processing has progressed from the designation by a manin-the-loop and hand over to a tracker to autonomous target recognition (ATR) and autonomous target acquisition (ATA) for both fixed and moving targets. An example is JSOW Unitary, which uses scene-matching techniques to correlate mission planning templates to the seeker video to establish an aimpoint to hand over to the tracker. Looking toward the future, EO seekers will continue to evolve to meet the individual market needs: multimode products such as NLOS (uncooled IR and SAL) to allow more flexible use of the weapons; uncooled IR for the most cost-sensitive applications; active EO seekers to determine detailed target characteristics; and, in general, increasing autonomy of the missile by the advances in ATA and ATR algorithms. • Dan Brunton dwbrunton@raytheon.com 2005 ISSUE 1 9
